"I think that the world needs to get over the fact that she was Hannah Montana when she was 16," Lovato told Katie Couric. "I guess my transition was a little easier because I went straight to rehab. I didn't twerk, I just went to rehab."

Lovato added that although people watched her and her peers become adults in some way, they don't know about everything that happened out of the spotlight.

"It's something nobody knows and nobody really knows who I am, and same with Selena [Gomez] and Jonas [Brothers], and everyone that has grown up in front of the public eye, and we're adults now... we're all in the process of doing that so go a little easy on us, America," she said.

Cyrus and Lovato began a friendship stint six years ago on the set of Hannah Montana.

Although she may not agree with everything Cyrus chooses to do, Lovato thinks Cyrus is smart and talented enough to get away with it and still be successful.

"A lot of artists take that route of shock value, and that's totally fine and that's great, but I think she has such an incredible voice that's overshadowed by some of the things that she's doing," Lovato said.

"It's her journey. She's having fun; she's being who she is. But everyone is on their different journeys right now and she's doing that and she's having fun and power to her."
